Reagents for Protein Stabilization

The stability of protein and antibody structure and function is dependent on a variety of factors such as temperature, freeze/thaw cycles, proteases and pH. For some proteins and
antibodies, function can be lost completely with a single freeze/thaw cycle and proteases can significantly degrade proteins and antibodies within hours even when kept at 4 °C.
These products minimize the risk to improve assay quality and accuracy.
